PUMP-VENT.

Specification of Letters Patent.

Patented Apr. 21, 1914.

Application filed April 23, 1913. Serial No. 763,127.

To all whom it may concern:

Be it known that I, JOSEPH F. HAENNIG, a citizen of the United States, residing at Masonville, in the county of Delaware and State of Iowa, have invented certain new and useful Improvements in Pump-Vents, of which the following is a specification.

My invention relates to automatic pump vents with special reference to an improvement upon Letters Patent issued to me on the 18th day of Feb. 1913, No. 1,053,382 and the object is to simplify the construction and render it more convenient and easier of operation and of less danger of getting out of repair than that set forth 1n the aforementioned patent.

The manner in which I construct and operate the same and the showing wherein it is differentiated from my former patent will be set out in the following specification when taken in connection with the drawings accompanving the same and forming a part hereof.

Figure 1 is a vertical view of my devlce. Fig. 2 is a vertical section through the cylinder and the member that takes the water from the cylinder and returns it to the cylinder. Fig.3 is a vertical view of the device with a vertical section of the water conducting member. Fig. 4 is a cross section through line X-X of Fig. 1. Fig. 5 shows a perspective view of the second member with part cut away showing valves therein. Fig. 6is a vertical section of Fig. 5.

Like characters of reference denote corresponding parts in each of the figures.

Referring to the drawings, 2 deslgnates the cylinder and 4 the pump rod. Within the cylinder is a plunger 5. This cylinder is provided with an opening 6 below the plunger 5. Around the openlng 6 is attached a water conducting member 9, which takes the water from the cylinder below the plunger and. delivers it back into the cylinder through the opening 8. In the member 9 just below the opening 8 is secured a valve seat 10. The valve consists of a weight 14 in circular form which rests upon the seat and closes an opening up through the seat 10 in the member 9 and also closes the open ing 8 into the cylinder. This member 9 has a cap 15 which covers the top of the member and is provided with a nut 16 to operate the cap to hold it firmly over the top of the member.

Against the side of the cylinder 2 and the member 9 is secured a second member 20 (shown in Figs. 5 and 6) which has an opening forming water communications both with the member 9 and the cylinder 2 at 22. It also opens into the member 9 by an opening 24. Above the opening 24 and on a line parallel with the valve seat 10 is a valve seat 25, which has an opening 26 therethrough, and upon this opening, or screwed into this opening, is a tubular valve seat 28. Over the tubular valve seat is a cap 30 which is considerably larger than the tubular valve seat. The member 20 is provided with a cap 32 which is operated by a nut 34. Through the cap 32 and nut 34 is a'valve port 35,

I which extends from a short distance above the cap or valve 30 and after it passes through the nut 34 is bent at substantially right angles. It will be seen that the cap 30 controls both of the valve ports 35 and 28 openmg one and closing the other at the same time.

The manner of operating my device is substantially as follows: The pump through the pump rod is started and as the water passes up in the cylinder 2 it-follows up the plunger 5 and then out through the opening 6 into the member 9 and on the reverse stroke, the water is forced from beneath'the plunger 5 through the opening 6 into the member 9. The water passes through the opening 24 in the member 20 and up through the pipe 28, and lifts the cap valve 30 and passes over the top of the tube 28 and down around said tube and under the lower edge of the cap, or valve 30 into the cylinder 2 and at the same time forces the cap 30 up against the seat of the port 35 preventing any water from passing through said port. A further stroke of the pump rod will raise the weight 14 off from the valve seat 10 and force the water up beneath the weight and out through the opening 8 into both the cylinder 2 and the member 20 and out of the member 20 into the cylinder. When the operator has ceased pumping, then the valve 30 drops down over the valve seat 28 and the weight 14 over the valve seat 10 and prevents all water passing down into the memher 9. Then the water that is above the top of the valve 35 will pass into the member 20 through the opening 22 and up out through the valve port 35 and drain all the water in the cylinder 2 above the top of the valve port 35. It will be seen by this mode of construction and operation that 1. In a device of the character described,

'10 a cylinder provided with two openings in .one side, a plunger in the cylinder between the openings, a member secured around the openings for taking the water from the cylinder and returning it to the cylinder, a weight controlled valve in the member, a

second member provided with water communications with the first member and the cylinder, a valve in the second member, and means connected with the second member for drawing off the water from the upper part of the cylinder when the pump has ceased pumping.

2. In a device of the character described, a cylinder provided with two openings, a member connected to the cylinder at the two openings and closed at one end, a weighted valve in said member, a second member opening into the first member and the cylinder, a valve in said second member between the two openings, and a valve in the second member for drawing oft the water from the upper part of the cylinder when the pump has ceased pumping.

3. In a device of the character described, a cylinder provided with two openings, a

member connecting the two openings, and forming water communications between the cylinder below the plunger and the cylinder above the plunger, a weight controlled valve in the first member, a second member having water communications between the first member and the cylinder, a valve in the second member on a plane substantially parallel with the valve seat in the first member, a cap over the valve, a second valve in the second member above the first valve and controlled by said cap for drawing oii the water from the cylinder after the pump has ceased pumping.

l. In a device of the character described, a cylinder provided with two openings in the side of the cylinder, a plunger in the cylinder between the openings, a water conducting member connected with the cylinder at both openings, a weighted valve in said member, a second member opening into the first, and into the cylinder and a valve in said second member that prevents the water which is in the second member and cylinder from returning back into the cylinder through the first member and draws oil the water from the cylinder above the second member.

In testimony whereof I afiix my signature in presence of two witnesses.
